Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a CRTSⅢ type track plate measuring frame. Background Art

[0002] Track slabs are new sub-track components with a plate-like structure that support and secure rails, distributing the loads transmitted by trains through the rails to the base beneath the slabs. CRTS III ballastless track slabs are a new type of unitized slab-type ballastless track structure with shoulder guards. They primarily consist of rails, fasteners, precast track slabs, reinforced self-compacting concrete (self-leveling concrete adjustment layer), limit stops, an intermediate isolation layer (geotextile), and a reinforced concrete base.
